IMPROVEMENT IN musauuroas;V

'ro ALL WHOM vIT MAY ooNc'EnN:

Be itv known that I, HIRAM TAYLOR, of Cincinnati, Hamilton county, Stato of Ohio, have invented new and useful Improvements in Lubricators; 'and I do hereby `declare the following to be a full, clear, and exact description thereof, reference -being had to the accompanying drawings, making part ofthis specification.

My invention consists, first, in supporting the regulating-rod of a lubricator by a contraction or inward projection inthe lower endof the hollow stem, so as to keep it from contact with the journal; second, in the employment of a rod of peculiar construction, the 'reversingof which `will vary or graduate the rapidity or freedom of delivery' of oil. In the accompanying drawings- Figure 1 is an axial section of a lubricator embodying my invention'.

Figure 2 exhibits `the parts detached.` Y i Figure-3 is a section on an enlarged scale ofthe lower end of the stem and its accompanying notched rod, which regulates `the flow of oil.

A is a. hollow glass sphere-designed to serve as the oil-reservoiri It is constructed with a perforated shank, a, over which a conical stopper or plug, B, is cast, of soft or fusible nietal. Previously to casting the metallic collar orplug, I bring the reservoir to a nearly red heat, and, having inserted a wooden spile in its neck, and placed the whole inel suitable mould, I pour in the metal.

The shank a is provided'with notches, a', into which theV metal of theplug B runs,` as it is cast around the shank, so as to serve as an anchor, together with the contraction of the nie-tal, as it cools, which permanently .and tightly-secures theplug B to the globe A. I

' C is the hollow cup-shaped stem, whose shank is chased to tit into the journal-box, the lower end thereof` fitting close to the revolving shaft. The cup c on the upper end of shank C lits tightly over the plug B, the parts being ground together. A

D is a solid rod, which serves as the oil-feeder. It passes loosely through the shank a, plug B, and stem C, a'nd is supported on the contracted end c of the stem C, Tbc'oil is drawn Iby the reirolving shaft or other moving part requiring lubricating from the globe through the space between the rod andthe holes through which it passes, the notch d in the rod D allowing it topass through the contracted end c. Should this arrange' ment give too free an allowance of oil, the rod can be reversed, as in lig. 2, and the unnotched end rest on the contracted mouth c,- the incompleteness of the fit allowing the oil to sup through, theimouth c in the quantity desired. v

The rod D may be furnished with a notch at each end, instead of 'asingle one, as shown at d, and these two notches should be of different dimensions, soriasfto permit of a greater or less flow of oil from-thc globe Af. i

In 4an inferior modifica-tion ofthe above, an entirely unnotched rod, D, may be used, and an opening made for a suicient passage of `the oil by a notch, c', of the stern C. The quantity of oil fed to the shaft may also be regulated to an indefinite extent by varying the size ofitherod D or notch cl.

' The oil-globe can be readily removed for filling, and, when returned, will resume itsformcr relation to the stationary portion withoutadjustment.-

In all -lubricators of this class which have heretofore been constructed, the glass reservoirs have been attached to the stems by means of cement of some hind, which, being li'able to crack by inequalities of ternperature and contact ofthe oil, orby the act of screwing or unscrewingthe lubricator from the journal-boxer other mechanical violence, would admit air to the interior of the globe, causing it to deliver its contents all at once, or even loosen and detach the globe entirely so as to spill and waste the content-s' about the room or'shopA Although I havehere shown'a lubricator formed in two separable parts, it is evident that my soft-metal collar is well adapted for use with those which are'in one piece and screw directly into the journal-box.

I claim h erein as new, and of my inventioni r 1. Supporting the rod D by the lower end c of the hollow stem out of contact with the journal, substantially'as set forth.V y 'A 2A. The notched or grooved rod D d, adapted, by reversing end for end, to change or graduate the freedom of delivery of oil, as herein explained.

In testimony of which invention, I hereunto set my hand.
